4.1
RAM/SFR area is located within data page 3 and provides access to the internal RAM
(IRAM, organized as X*16) and to two 512 Byte blocks of Special Function Registers
(SFRs). C161U provides 3 KByte of IRAM, see Figure 10.
The internal RAM serves for several purposes:
• System Stack (programmable size)
• General Purpose Register Banks (GPRs)
• Source and destination pointers for the Peripheral Event Controller (PEC)
• Variable and other data storage, or
• Code storage.
